ruby-on-rails - result.credit_card_verification 即使在 braintree 出错时也返回 nil

Question

我正在使用 braintree 进行支付处理，我正在尝试获取 Processor Response Codes来自 Braintree 和 Ruby。

这是我的代码:

 verification = result.credit_card_verification
 response_code = verification.try(:processor_response_code)

即使有错误，我也得到验证为 nil。

还有其他方法可以获取处理器响应代码吗？

我从 here 得到了这段代码

这是我的 result.erros :

:errors: !ruby/object:Braintree::Errors
  errors: !ruby/object:Braintree::ValidationErrorCollection
    errors: []
    nested:
      :customer: !ruby/object:Braintree::ValidationErrorCollection
        errors: []
        nested:
          :credit_card: !ruby/object:Braintree::ValidationErrorCollection
            errors:
            - !ruby/object:Braintree::ValidationError
              code: '81707'
              attribute: cvv
              message: CVV must be 4 digits for American Express and 3 digits for
                other card types.
            - !ruby/object:Braintree::ValidationError
              code: '81713'
              attribute: expiration_year
              message: Expiration year is invalid.
            - !ruby/object:Braintree::ValidationError
              code: '81703'
              attribute: number
              message: Credit card type is not accepted by this merchant account.
            - !ruby/object:Braintree::ValidationError
              code: '81715'
              attribute: number
              message: Credit card number is invalid.
            nested:
              :billing_address: !ruby/object:Braintree::ValidationErrorCollection
                errors: []
                nested: {}

处理 Braintree result objects是进步的。

如果 result.success? 为 false，则检查 result.errors，它表示 validation errors .

如果result.errors 为nil，则请求有效。在这种情况下，您将拥有一个 transaction 或 verification 对象，就像 result.success? 是 true 一样。

然后您可以查看result.verification的status、processor_response_code、gateway_rejection_reason等。
